【Problem description]
When you log on to the Oracle database with sqlplus, the message "ORA-28002: the password will expire 7 days later" is displayed ".
[Cause/trigger factor]
This is because "password_life_time = 180 days" is set in the default profile in oracle11g by default.
[Impact and risk]
Impact
After the password expires, the business process has an exception connecting to the database, affecting service usage.
Problem occurrence frequency
After the database password expires, the connection will fail once the business process restarts.
[Solution]
Follow these steps:
1. Check the user's proifle, which is generally default:
SQL> select username, profile from dba_users;
2. view the password validity period settings of the specified profile (such as default:
SQL> select * From dba_profiles s where S. Profile = 'default' and resource_name ='Password_life_time';
3. Change the password validity period from the default 180 days to "unlimited ":
SQL> alter profile default limitPassword_life_timeUnlimited;
After modification, the database does not need to be restarted and takes effect immediately.
4. After modification, the account has not been prompted ORA-28002 warning will not again encounter the same prompt;
The account that has been prompted must change the password again, for example:
$ Sqlplus/As sysdba
SQL> alter userSMSCIdentified by <original password> ---- No new password is required
The oracle11g startup parameter resource_limit takes effect regardless of whether it is set to false or true. Therefore, you must modify the password in the preceding method. The preceding account name must be changed based on the actual account name.
